Effect of interferons, transforming growth factor beta1, bone morphogenetic protein 2 and bone morphogenetic protein 4 on SMA abundance in rat HSCs. Sub-cultured HSCs were incubated with water only, 500 U/ml of different IFNs for 6 days and the abundance of SMA in HSCs was documented in panel A, while sub-cultured HSCs were treated with 5 ng/ml of transforming growth factor beta1, 5 ng/ml of bone morphogenetic protein 2 and 5 ng/ml of bone morphogenetic protein 4 for 4 days and the abundance of SMA in HSCs was presented in panel B. HI indicates heat-inactivation.
